A man wants to cut down a tree in his yard. To ensure that the tree doesn't hit anything, he needs to know the height of the tree. He measures his distance from the tree at 11 meters and the angle of elevation to the tree at 61 degrees. What is the height of the tree to the nearest tenth of a meter?

19.8m

Step-by-step explanation:

In the attached diagram:

This forms the right triangle ABC.

We want to determine the height labeled h.

Using Trigonometry:

The height of the tree is 19.8 meters to the nearest tenth of a meter.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
